In Universe the modifier SAMPLED nn selects every nn'th record. For
example, SELECT MYFILE SAMPLED 50 selects every 50th record. That way

SAMPLED keyword with a D on the end will go thru the entire file.
SAMPLED 1000 will get every thousandth record as it reads through the file.
SAMPLED 1000 SAMPLE 2000 will do the same, but then stop after it builds a
list of 2000. That is, after it's read thru the 1st 2 million keys.
